Rated 4 out of 5 by from Best chainsaw I have ever owned. Great product! Well built. Plenty of power for a home owner. Used to clear some trees and cut firewood.Love the easy access to adjust tension on the chain.Cover, chain, and bar are easy to remove and replace. Makes clean up a snap.

Rated 4 out of 5 by from Back up saw to my Husky Bought this saw as a back up for my 25 year old Husky. Got it just before hurricane Irma hit. Has been going since. Hard to find replacement chains this week with all the power outages and downed trees. Been helping the elderly neighbors, using both saws. Hope it holds up like my Husky has and I'll be happy.

Rated 4 out of 5 by from Ms251 woodboss is a good saw, but I have noticed... I bought this saw (ms251 withought easy start or easy chain tensioner) over a month ago. Cut down a dying/dead 10" apple tree days after purchasing. The job was a breeze (aside from the heat in NC), and the chain performed great. I personally have not had issues with starting the chainsaw. I believe many people who are experiencing these issues (admitted by some) are Not following the appropriate steps. If cold, move choke lever to cold choke. Pull the starter rope until it starts to fire, making sure you don't exceed 3-4 pulls as to not flood the engine. Next, move lever to the "starting choke" position, and pull starter rope to finish the startup. If warm, or if you've started it already that day, begin starting the saw in the "starting choke" position. Simple as that. My only issue with the saw, after cutting down a handful of trees, is that the chain is not being oiled sufficiently. Oil is coming out (as I removed the bar/chain and started the saw briefly to observe this), but not enough comes out to properly lubricate the chain. I have been manually lubricating the chain before, and sometimes, during a job. This seems to be a recurring issue amongst owners of this saw. It's important to have the chain lubricated so that the chain, bar, and clutch down overheat, and so the chain doesn't dull out prematurely. While this is unfortunate, and somewhat annoying, I still enjoy the saw, and am impressed with its performance.

Rated 5 out of 5 by from Best bang for your buck I received this beauty from my family on my 63rd Birthday, I can tell you - I am very pleased indeed! I have felled quite a few Ash trees that had emerald bore infestations on my property. These aren't sissy trees, they are good size and the Wood Boss held up to it's name.Easy to start - easy to operate as long as you are conscious of your surroundings and stay alert and safe.Good weight distribution and pretty quite too.

Rated 5 out of 5 by from Great balance of weight and power The MS 251 Wood Boss is a great homeowner/woodcutter saw with an ideal balance of weight, bar length and power for tasks around the home/ranch and for firewood cutting. Starts easily and runs great - easy to keep in tune. I ran Stihl chainsaws years ago professionally and I'm very pleased with this 'small' saw - it has the same quality design and construction as the big pro saws I used to use.

Rated 5 out of 5 by from Another great Stihl saw I've owned several Stihl chainsaws in the past and just replaced a decades-old 025 16" that just finally gave out. This new saw is more powerful,slightly longer (18") bar works as charmingly as my previous Stihls. I like some of the newer features like the quarter-turn caps for bar oil and fuel.Looking forward to many good years of service!
